This hack is very enjoyable and not as hard as I thought. There are some hard levels, yes, but I can beat other levels without dying. And this hack made me suffer into it, I love some graphics here, like those big dinos, that split fire and boos (when they open their mouth, they looks funny to me). There a few grammar mistakes, but my overall point is 5/5. Great job!
I haven't played SMW hacks in about a year now and every now and then there comes a hack that just draws me in again.
This was it for me.
It's easy to dismiss this as "Replace Mario with [Input Alternate Sprite Here] part 57" with long paragraphs in between levels that 10% of player might read and actually get invested in but this hack is so so much more that those. I'd go as far as saying this is as good as or maybe one step down from The Sicari series which are among my favorites.
The level design is subtle. Instead of overloading the screen with munchers and chucks, hazards are minimalistic but placed at spots a player is likely to land. It's hard but fair like Chomp not sadistically hard like Colossus.
Work of advice though is don't read the dialogue because it might decrease the overall experience for you.
I think this hack deserves a 4.5 but since we don't have that option, I'm giving it a 5.
I underestimated this hack's difficulty, even with the warnings lol. You have a pretty sadistic idea of level design right there, and as a result, this hack has been reclassified as very hard.
That said, It's very nice to see the vast improvement this hack is over its original version, and I can see that you put quite the bit of love into it. It worked fine for the most part, but it could use a bit of polish. On the title screen, you can hear the player jumping around off-screen which is a bit of an awkward first impression. There were also the issue of silent bullet bills and enemies that could easily trap you in some areas. The final boss also caused severe slowdown with his spawned in enemies.
Overall, I think you've done a nice job, even if you did give me a hard time ;)
